Description

Technical Field

[0001] This utility model belongs to the field of welding equipment, and in particular relates to an automatic welding machine for sprocket cores. Background Technology

[0002] Chain drive is a reliable and adaptable mechanical transmission method that transmits power through the meshing of a chain and sprockets. The sprocket, as the core component, directly affects system performance due to its design and material selection. Welded sprockets are manufactured using a welding process. Compared to traditional cast or machined sprockets, their key feature is the welded combination of the toothed ring and the sprocket core, balancing strength and flexibility.

[0003] Currently, sprocket manufacturing still relies on manual welding by workers. The skill level of these workers makes production quality uncontrollable, potentially leading to uneven welds and inconsistent strength. This can easily cause strength fluctuations and stress cracks, increasing the risk of failure under heavy loads. Furthermore, manual welding is typically slow and inefficient, thus increasing production costs. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 5 This utility model embodiment provides an automatic sprocket core welding machine for welding sprockets 5, the sprocket 5 including a core 51 and a gear ring 52, comprising:

[0032] Base 1;

[0033] Clamping assembly 2, used for clamping wheel core 51, includes:

[0034] The rotating seat 21 is rotatably mounted on the base 1 via the rotating shaft 211, and multiple movable claws 22 are movably mounted on it.

[0035] An adjusting disc 23 is located inside a rotating base 21. A toothed disc 231 is fixedly provided on the adjusting disc 23. A spiral tooth 232 is fixedly provided on the contact surface between the adjusting disc 23 and the movable claw 22. A tooth groove 221 that matches the tooth 232 is fixedly provided on the movable claw 22 at the position corresponding to the tooth 232.

[0036] Adjusting gear 24 meshes with gear disc 231 and is rotatably mounted on the side of rotating seat 21, with a wrench groove 241 fixedly opened at its end;

[0037] Drive component 3 is used to drive the rotary seat 21 to rotate;

[0038] The welding assembly 4 includes a welding torch 42 for welding the wheel core 51 and the gear ring 52, the welding torch 42 being fixedly mounted on the base 1 by an adjusting rod 41.

[0039] In practical application, the adjusting gear 24 is rotated by tools such as a wrench. Under the meshing action of the adjusting gear 24 and the gear plate 231, the adjusting plate 23 is rotated axially as a whole. Under the meshing action of the convex tooth 232 and the tooth groove 221, the movable claw 22 is moved radially to clamp the wheel core 51 and set the gear ring 52 on the wheel core 51. The adjusting rod 41 is adjusted to place the welding nozzle of the welding gun 42 at the welding position of the gear ring 52 and the wheel core 51. Then, the rotating seat 21 is driven to rotate axially by the driving component 3, which in turn drives the sprocket 5 to rotate. The welding work of the gear ring 52 and the wheel core 51 is achieved by the welding gun 42.

[0040] In this embodiment, the movable claw 22, in conjunction with the adjusting disc 23 and the adjusting gear 24, clamps the sprocket 5, making it convenient for workers to clamp. The rotating seat 21 drives the sprocket 5 to rotate, facilitating the welding of the wheel core 51 and the gear ring 52 by the welding torch 42. Compared with traditional welding methods, it is easier to control the welding quality and improve the processing speed. At the same time, the operation of this equipment is simple and easy for workers to learn and use.

[0041] Please see Figure 2 and Figure 3 In a preferred embodiment of this utility model, the driving component 3 includes:

[0042] Motor 31 is fixedly installed at the bottom of base 1;

[0043] The drive gear 32 is installed in the inner layer of the base 1 and is fixedly connected to the power output end of the motor 31.

[0044] Driven gear 33 is fixedly mounted on the outside of rotating shaft 211 and meshes with drive gear 32.

[0045] In practical application, the motor 31 drives the drive gear 32 to rotate, and the meshing action of the drive gear 32 and the driven gear 33 drives the rotating shaft 211 to rotate, thereby driving the rotating seat 21 to rotate as a whole.

[0046] In one embodiment, the transmission method of the drive component 3 can also be set to various types, such as chain and sprocket drive, belt and pulley drive, direct motor drive, etc., as long as it can drive the rotating seat 21 to rotate as a whole. This embodiment does not impose too many limitations here.

[0047] Please see Figure 2 and Figure 5 In another preferred embodiment of the present invention, a cleaver 222 is fixedly provided on the movable cleaver 22, and the cleaver 222 cooperates with the movable cleaver 22 to clamp the wheel core 51.

[0048] In practical applications, this embodiment uses a set of chucks 222 in conjunction with multiple movable chucks 22. The radial movement of the movable chucks 22 enables the clamping and positioning of the inner ring of the wheel core 51. Based on the radially movable chucks 22, it can adapt to wheel cores 51 with different inner diameters, thereby ensuring the clamping and positioning effect of the wheel core 51.

[0049] Please see Figure 4 and Figure 5 In another preferred embodiment of this utility model, the movable claw 22 is also provided with a threaded hole 223, and a screw 25 is installed in the threaded hole 223 by threaded engagement. The screw 25 is used to support and position the gear ring 52.

[0050] Furthermore, a top head 251 is fixedly installed at the top of the screw 25. The top head 251 is made of an elastic material and is in contact with the surface of the gear ring 52 by compression.

[0051] In practical applications, this embodiment uses a screw 25 and a top head 251 to support and position the gear ring 52, making it easy to adjust the relative position of the gear ring 52 on the wheel core 51 in the axial direction. This allows it to adapt to wheel cores 51 and gear rings 52 of different thicknesses, thus providing greater applicability and ensuring welding results.

[0052] Please see Figure 1 and Figure 5 In another preferred embodiment of the present invention, the movable claws 22 are configured to be at least three, and the movable claws 22 are arranged radially in a ring-shaped manner along the clamping assembly 2.

[0053] In practical applications, this embodiment, by setting the number of movable claws 22, can effectively ensure the coaxiality of the wheel core 51 and the rotating seat 21 during clamping, thereby ensuring the welding quality when the rotating seat 21 is driven to rotate to weld the wheel core 51 and the gear ring 52, and further avoiding the problem of uneven weld seams.

[0054] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
